COMPOSITION FOR MAKING BRICK.

To all whom it may concern Be it known that I, WILLIAM L. JONES, acitizen of the United States, residing at Atlanta, in the county ofFulton and State of Georgia, have invented certain new and use fulImprovements in Compositions for Making Brick, of which the following isa specification.

This invention relates to a composition of matter for making a concretebrick.

The object of my invention is to compound a brick at a reduction in costover the bricks as prepared now-a-days, and which will possess thedesirable features to be found in bricks and stand any water-proofingtest to which it may be submitted in use.

The leading feature of my invention contemplates the production of abrick in connection with which there will be no burning and in whichthere will be a total absence of clay,-incidents tending largely toincrease the expense of manufacture, as known to those skilled in theart.

Bricks made in accordance with my compound will be water resisting andmay with great advantage be used in foundations for rivers and generallyfor ornamental work. The manufacture of bricks as now carried on hasresulted in the molded product losing the tenancious properties forresisting moisture shortly after it has been subjected to a se- Verewater test, and wherever a waterproof brick has been produced it wasdevoid of the essence of solidity common to concrete bricks, beingbesides too costly and of little value from a commercial standpoint. Theconcrete brick formed by compounding the ingredients to be statedeliminates some of the ingredients most commonly used in brickssupplanting these by others which I have found upon test and experimentto possess the qualities most needed in a commercially successful brickof the character described.

For compounding the concrete brick the following ingredients will beused in the proportions set forth or thereabout:

Isinglass 1 per cent. Coloring 8 Creosote 1 Cement 35 Pulverized granite35 Sand 2O It wilitbe understood that the above pro- Specification ofLetters Patent.

portions of the ingredients may be varied and modified, in practicewithout sacrificing any of the qualities of the concrete brick which Ihave produced. It will be obvious that a given number of pounds of theabove ingredients may be used to produce a given number of bricks. Thebricks thus produced will be pressed bricks and will diifer from othersin needing no clay or burning to give them the desired consistency andsolidity. The concrete brick will be made in cast steel molds of thestandard size, preferably so that the product may be of standard weight,and will be formed under a pressure of two hundred pounds, and molded intwenty-one shades and tints; the ingredients used are of a kindrednature and when mixed with the proper per cent. of each will make a verysolid, sound, moisture resisting and a relatively moisture-proofconcrete brick. These ingredients are all mixed and thoroughly moistenedwith water, but what water is used in making the bricks will dry out,and when finished, water will have no effect on the brick at all.Plaster can be prepared out of the same ingredients using only, adifferent proportion and for finish the compound can be mostadvantageously used.

The ingredients used cooperate to give the concrete brick the solidity,tenacity, and consistency re uired. The isinglass gives the brick aglittering effect, especially on bright and fair days; the coloring isused to make it as nearly like clay as possible, and the twenty-oneshades hereinbefore mentioned subserve a variety of tint; the creosoteis used to make the bricks slip out of the molds and in order to give ita real slick and glossy finish; cement is the strengthening agent whilethe granite makes up the body of the concrete brick; sand is the bindingvehicle and holds together the rest of the ingredients.

I claim and desire to secure by Letters Patent:

A concrete brick composed of isinglass, coloring, creosote, cement,pulverized granite and sand.

In testimony whereof I aflix my signature in presence of two witnesses.
